Hemolymph is comparable to blood in a closed circulatory system. In open circulatory systems, hemolymph is propelled by a heart through short arteries and into spaces called sinuses surrounding tissues and organs. Hemolymph reenters the heart through pores that are usually equipped with valves. Hemocoel refers to the collective hemolymph-filled body sinuses. The coelom is not the same as the hemocoel, and is usually very reduced in development after the embryo stage. The hemocoel becomes the main body cavity in adults.

C. hemocoel
Where is a clams coelom?
Clams do not have a coelom. They have a body cavity known as a hemocoel, which is filled with blood and surrounds their internal organs. This hemocoel is responsible for transporting nutrients, gases, and wastes throughout the clam's body.
Does arthropoda have coelom?
Yes. Arthropods have body cavities (coelomates); their main internal cavity is a hemocoel, which accommodates their internal organs and through which their blood circulates - they have open circulatory systems. Arthopods come from a lineage of animals that have a coelom, a membrane-lined cavity between the gut and the body wall that accommodates the internal organs. The coelom of the arthropod is reduced to small areas around the reproductive and excretory systems. Visit http://smackers0609.blogspot.com/Yes.

Do roundworms have no coelom a pseudocelom or a true coelom?
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
What is the difference between schizocoelous and enterocoelous?
Schizocoelous found in protostomes and this is destriptive for coelom development during which archentron froms and coelom begins as splits within the solid mesodermal mass. Entrocoelous found in deuterostomes and coelom development during which the mesoderm arises as lateral outpocketing of archentron with hollows that become coelomic cavity.
What do you mean by true coelom?
The coelom is the body cavity of an animal. A true coelom is a body cavity that is complete from mouth to anus with no breaks; there are animals that have pseudocoeloms - mouths and anuses but no solid connection between the two.
Do flatworms have no coelom?
Yes, flatworms do not have a true coelom. They have a solid body structure without a cavity between their gut and body wall, which distinguishes them as acoelomates.
What is a hemocoel?
A hemocoel is a body cavity in invertebrate animals that contains circulating body fluids, such as blood. It functions like a circulatory system, transporting nutrients and waste products throughout the organism's body.
Do roundworms have coelom?
Yes. However, this is not a true coelom. Roundworms are pseudocoelomates -- their mesoderm lines the endoderm and ectoderm, but there is no connection between the two. Therefore, it does not satisfy the definition of a coelom. However, since there is a body cavity still, this animal is said to be a pseudocoelomate.
What is the differences between the coelum and acoelum?
The coelom is a fluid-filled body cavity between the intestines and the body wall of some higher metazoans. It is lined with a mesodermal epithelium. The coelom is formed within the mesoderm of the embryo.
What is the difference between coelomate and acoelomate?
Acoelomate is an animal that lacks a body cavity or a coleom.
What is coelom and give its types?
coelom is a fluid filled cavity within the body between the epidermis and gut it is derived from mesoderm there are three types of coelomic cavity they are coelomemates psuedo coelomates and acoelomates
